Given numbers are 820,475,845,149

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 820,475,845,149 is 1961599900.

Find LCM of 820,475,845,149 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

5 x 164 x 95 x 169 x 149 = 1961599900

Therefore, the lowest common multiple of 820,475,845,149 is 1961599900.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

820 x 475 x 845 x 149 = 49039997500

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

475 : 1, 5, 19, 25, 95, 475

845 : 1, 5, 13, 65, 169, 845

149 : 1, 149

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,475,845,149, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

475:5x 5x 19

845:5x 13x 13

149:149

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 5 = 25

Therefore, the value for common factors is 25.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 49039997500/(1x25)

LCM = 49039997500/25

LCM = 1961599900

Thus, we can understand that the LCM of 820,475,845,149 is 1961599900.
